[0032] In order to make the objects, features and advantages of the present application more obvious and understandable, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0033] The utility model inventor has found through analysis of the prior art that as sweepers become more and more popular, users have higher and higher requirements for deep cleaning effects. How to improve deep cleaning capabilities has become a challenge for the entire industry. Reducing noise and improving self-cleaning effects are also pain points in the industry.

[0034] The main technical problem solved by the utility model is to improve the cleaning ability of the drum and reduce the system noise.

[0035] In order to solve the above technical problems, the utility model adopts a technical solution: a scraper that can be automatically extended and retracted is arranged obliquely above the drum, and pressure is applied to the drum through the scraper. The automatic extension and retraction of the scraper is achieved by a symmetrical compression spring structure.

[0036] The utility model has the beneficial effects of applying dynamic pressure to the drum through the scraper structure with springs, enhancing the self-cleaning effect of the drum, and increasing the pressure on the ground when the drum is working. The cleaning effect of floor washing is improved, and the active gap of the drum is reduced, and the vibration noise is reduced. Due to the expansion and contraction characteristics of the spring, the life of the drum mop is extended, and the frequency of replacing the drum by the user is reduced.

[0037] In the embodiment of the present application, compared with the prior art problem that "the existing roller is easy to get dirty, cannot perform self-cleaning, the roller mop has a short lifespan, and the cleaning effect is poor", the present application provides a solution of "arranging an automatically retractable scraper obliquely above the roller", specifically: comprising a roller assembly 1, a roller bracket 2, a scraper spring assembly 6, and a scraper assembly 5 for cleaning the roller assembly 1; the bottom of the roller bracket 2 wraps the roller assembly 1, and the scraper assembly 5 and the scraper spring assembly 6 are arranged between the roller bracket 2 and the roller assembly 1; the roller assembly 1 includes at least two rollers; the scraper assembly 5 is arranged vertically with the roller assembly 1, and the scraper spring assembly 6 is sleeved on one end of the scraper assembly 5. The scraper spring assembly 6 and the scraper assembly 5 solve the problem that "the existing roller is easy to get dirty, cannot perform self-cleaning, the roller mop has a short lifespan, and the cleaning effect is poor", and the double-roller structure is used, and the two rollers contact the ground at the same time to improve the cleaning effect of floor washing, while offsetting the influence of rolling friction on robot control. The scraper structure with springs can exert dynamic pressure on the drum, enhancing the drum's self-cleaning effect, while increasing the pressure on the ground when the drum is working. This improves the cleaning effect of the floor, while reducing the active gap of the drum and reducing vibration noise. The elasticity of the spring also extends the service life of the drum mop, reducing the frequency of users replacing the drum mop.

[0038] Reference Figure 1-4 , shows a schematic structural diagram of the scraper structure of the utility model, which may specifically include the following structure: comprising a roller assembly 1, a roller bracket 2, a scraper spring assembly 6, and a scraper assembly 5 for cleaning the roller assembly 1; the bottom of the roller bracket 2 wraps the roller assembly 1, and the scraper assembly 5 and the scraper spring assembly 6 are arranged between the roller bracket 2 and the roller assembly 1; the roller assembly 1 includes at least two rollers; the scraper assembly 5 is vertically arranged with respect to the roller assembly 1, and the scraper spring assembly 6 is sleeved on one end of the scraper assembly 5.

[0039] Next, a scraper structure in this exemplary embodiment will be further described.

[0040] In one embodiment of the present application, the scraper assembly 5 and the scraper spring assembly 6 are provided between the drum bracket 2 and the drum assembly 1. The scraper assembly 5 is vertically arranged with respect to the drum assembly 1, and the scraper spring assembly 6 is sleeved on one end of the scraper assembly 5.

[0041] In a specific embodiment, the scraper spring assembly 6 exerts a strong effect on the scraper assembly 5 , thereby enabling the scraper assembly 5 to exert a strong effect on the roller assembly 1 .

[0042] In one embodiment of the present application, the scraper assembly 5 includes a first scraper 51 and a second scraper 52; the first scraper 51 is arranged perpendicular to the cross section of the first roller 11; the second scraper 52 is arranged perpendicular to the cross section of the second roller 12; the first scraper 51 and the second scraper 52 have the same shape.
